CONSTRUCTION OF CABLE- RAILROADS.

SPECIFICATION formingpart of Letters Patent No. 237,814, dated February15, 1881.

Application filed December 11, 1880.

To all whom it may concern:

Be it known that I, HENRY OAsEBoLT, of

i the city and county of San Francisco, and State of California, haveinvented certain Improvements in the Construction of Endless Gable- Waysand I hereby declare the following to be a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making part of this specification, in which Figure 1 is a perspectiveview of one of the cast-iron brackets used in my improved construction.Fig. 2 is a plan view of the same. Fig. 3 is a face View of the same,showing the end of the tie and slot-rail in position. Fig.4 is avertical longitudinal section through the line 00 w of Fig. 2. Fig. 5 isa perspective view of the frame-work for the tunnel and track. Fig. 6 isa vertical cross-section of the same.

In all cable-ways for the transportation of street-railway cars by meansof an endless traveling cable laid under ground it is highly desirabletohave theedges of the slot through, which the gripe-shank passesadjustable to and" from each other, in order to compensate for unequalwear, warping of the slot-rails, or,

when occasion requires, to raise the cable through the slot and abovethe surface. It is also desirable to construct the slot-rails in themost economical manner and still retain great strength, and the purposeof my invention is to attain these objects.

My invention consists, first,in an adjustable cast-iron bracket securedto the ties and supporting the slot-rails; secondly, in a flat slotrailrolled with a heavy bead or rib on one edge; and, thirdly, in certaindetails of construction, as hereinafter more fully described andclaimed.

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the manner in which I have carried it out.

In the said drawings, J J are the foundationtimbers, which are laid atthe bottom of the trench into which is to be built the tube or tunnel,these timbers J being provided with ribs K, to sustain the thrust of thesheathing, as hereinafter set forth. Upon J rest posts L, which, inturn, support the ties B B, on

(No model.)

which rest the stringers N N to receive the rail 0. The distance betweenthe posts L L and the ends of the ties determines the width of thetunnel opposite their respective positions.

Upon the end of each tie is a cast-iron bracket, A, projecting over theend of the tie toward the central line of the tunnel. The faces of thesebrackets sustain the slot-rails H H, which are left sufficiently farapart to form a slot, R, for the passage of the shank of the griper. Thebrackets A are cast with slots D, through which pass bolts 0, to securethem to the ties, and with holes, through which pass bolts I, to fastento them the slot-rails, and on their faces they have projecting ledges i1, upon which rest the lower edges of the slotrails, and on the sidesadjacent to the lowest points of their faces are right-angle-triangnlarlugs a, to receive and sustain the ends of angle-iron stringers P, theupper edge of the angle-iron stringer resting against the lower edge ofthe slot-rails H, to prevent the entrance of dirt into the tunnel.

The verticallyarranged planks S, which form the body of the tunnel, havetheir lower ends resting against ribsK on thefoundationtimbers, andtheir upper ends rest against the angle-iron stringers PP. The sidesurfaces of the brackets, ties, and posts are all in line, andconsequently the edges of the planks S set close against all of them,and leave no openings for the earth to enter the tunnel when theframework is covered.

Experiment teaches me that the form of slotrail shown, having the heavyrib O and the downwardly-projectin g web or flange 19, embodies greatwearing capacity, ease of fastening, and economy of production. Idescribe this slot-rail with the heavy rib O, in contradistinction tothe slot-rails heretofore used, made of angle-iron rolled for thepurpose, which are liable to be mashed down along the edges of the slot,whereas my slot-rail is in form the same with the ordinary commercialflat rail used for street-railroads, and the heavy rib offers aresistance to the wheels of heavy vehicles that prevents any distortionat the edges of the slot. The slots D in the brackets A allow an amountof longitudinal movement which to the same extent moves the attachedslot-rails H, and consequently increases or diminishes the width of theslot upon bolts C being loosened up and the bracket forced forward orrearward.

5 Hatingt-hus described inyinvention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a cable-wireway, the adj ustahle brackets A, adapted to sustainthe slot-rails at- IO taehed to and in combination with the ties B,

for the purpose set forth.

2. In combination with a tunnel adapted to contain a cable for anendless wireway, the

slot-rails H, having a heavy rib, O, and a depending web, 1),substantially as described, for 15 the purpose set forth.

3. The bracket A, provided with lugs (Ht, in combination with theangle-iron stringer P, substantially as and for thepurpose described.

In witness whereof I have hereunto set my 20 hand.

HENRY GASEBOLT.
